What is the rating of the KM III lifeline?

• A. 44 kN Rating (9891 lbf)
• B. 40 kN Rating (8992 lbf)
• C. 41 kN Rating (9217 lbf)
• D. 42 kN Rating (9390 lbf)

Answer: (A)

A lifeline’s rating represents its certified strength—the maximum load it can resist before it risks failing, expressed as a minimum breaking strength. For the KM III lifeline, the official rating is 44 kN, which is about 9891 pounds of force. This value comes from standardized testing and tells you the rope’s capacity in rescue scenarios. It doesn’t mean you should load the rope to that limit in use; rather, it’s the strength benchmark used when selecting equipment and designing safety systems. The other options would indicate a weaker rating, which does not match the published specification for this lifeline. So the correct rating is 44 kN (9891 lbf).
